LIFTING-ROD COLLAR'FOR SPINNING-FRAMES.

Specification of Letters Patent. Patented; Sept. 21, 1920.

Application filed February 19, 1920. Serial No. 359,920.

To all whom it may concern:

Be it known that I, J OHN T. CoTHRAN, a citizen of the United States, residing at Spartanburg, in the county of Spartanburg and State of South Carolina, have invented a new and useful Lifting-Rod Collar for Spinning-Frames, of which the following is a specification.

This invention relates to collars for use in connection with the lifting rods of spinning frames. Rods of this character have heretofore utilized bearing collars which are fitted tightly around them. These collars, however, become choked with lint and interfere materially with the operation of the machine.

One of the objects of the present invention is to provide a collar for a lifting rod which is so shaped as to give suflicient bearing points to insure proper operation but at the same time allow lint and the like to pass therethrough so that the parts will not become choked.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of a portion of a spinning frame with the lifting rod in position.

Fig. 2 is an elevation of the collar for the lifting rod.

Fig. 3 is a section on line 8-3, Fig. 2.

Referring to the figures by characters of reference 1 and 2 designate the rails of the frame which are of the usual construction, and above which is arranged a rail 3 to which is secured the upper end of a lifting rod 4. This rod extends downwardly through the rails 1 and 2 and, where it passes through the said rails 1 and 2, it is mounted within split sleeves one of which has been shown in detail in Figs. 2 and 8.

Each of these sleeves, which have been intangular opening 10 therein through which the lifting rod 4 projects, the corner por-' tions of the opening, however, being provided with inwardly extending ribs 11 presenting four bearing points for the lifting rod. Each of the collars or sleeves 6 is held in place by a set screw 12 extending into the rail and projecting into a recess 13 in the collar.

It will be obvious that by providing a collar such as described lint or the like will not clog in the same and interfere with the operation of the parts but will, instead, pass freely downwardly between the bearing ribs 11.

Collars such as described can be used wherever necessary, as for example, on the twister frame, the spooling frame as well as the spinning frame. 1

What is claimed is:

1. A collar for lifting rods, comprising opposed sections defining a substantially angular opening therethrough for a lifting rod, there being spaced bearing portions extending inwardly from the wall of the opening.

2. The combination with a lifting rod, and rails through which the rod extends, of a collar secured within each of the rails and comprising opposed detachably connected segments defining a substantially angularopening through which the rod extends, said rod being cylindrical, and spaced bearing portions within the opening for sliding, engagement by the rod, there being clearance spaces between said bearing portions for the free passage of lint through the collar.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JOHN THOMAS COTHRAN.
